There are five main causes of desertification. These are: Climate Change – hotter and drier conditions are increasing the risk of land turning to desert; Removal of trees for fuel – cutting down trees to use the wood for fuel leads to roots dying.
Do deserts serve a purpose?
The dry condition of deserts helps promote the formation and concentration of important minerals. Gypsum, borates, nitrates, potassium and other salts build up in deserts when water carrying these minerals evaporates. Minimal vegetation has also made it easier to extract important minerals from desert regions.
Can you live in a desert?
Deserts are perhaps one of the most difficult places to live. Because humans need so much water, surviving in deserts is very difficult. Not only is it difficult for humans to survive in deserts – it is also hard for animals, plants and other forms of life to live.
Is the Sahara growing?
While the desert waxes and wanes with the drought that comes with the changing seasons, declining rainfall combined with deforestation and soil degradation has seen it grow. Over the past century, the Sahara desert has been expanding by more than 7,600sq km a year and is now 10% larger than it was in 1920.

- Low Rainfall. Low rainfall is the most obvious environmental factor in an arid area.
- Intense Sunlight and Heat.
- Wide Temperature Range.
- Sparse Vegetation.
- High Mineral Content.
Will the Sahara be green again?
The next Northern Hemisphere summer insolation maximum — when the Green Sahara could reappear — is projected to happen again about 10,000 years from now in A.D. 12000 or A.D. 13000. So, a future Green Sahara event is still highly likely in the distant future.
